    <title>Introduction to Doxygen</title>

    <para>
      The <application>Doxygen</application> package contains a documentation
      system for C++, C, Java, Objective-C, Corba IDL and to some extent PHP,
      C# and D. It is useful for generating HTML documentation and/or an
      off-line reference manual from a set of documented source files. There
      is also support for generating output in RTF, PostScript, hyperlinked
      PDF, compressed HTML, and Unix man pages. The documentation is extracted
      directly from the sources, which makes it much easier to keep the
      documentation consistent with the source code.
    </para>

    <para>
      You can also configure <application>Doxygen</application> to extract
      the code structure from undocumented source files. This is very useful
      to quickly find your way in large source distributions. Used along with
      <application>Graphviz</application>, you can also visualize the relations
      between the various elements by means of include dependency graphs,
      inheritance diagrams, and collaboration diagrams, which are all generated
      automatically.

      There is no real configuration necessary for the

      documentation, then you must have <xref linkend="texlive"/> installed.

      you must have <xref linkend="gs"/> installed.
